Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention provides a buckle member having a box-like overall shape and having guide passages at the top and bottom, and a buckle member that is inserted into the guide passage and locked from both the front and back sides. To provide a binding band device made of synthetic resin that combines a band member with a band member, in which both sides of the band member can be used, binding and unbinding can be performed in any direction, and operation is easy especially when miniaturized. The present invention provides a band device that can perform the following functions.

[Prior art]

2. Description of the Related Art Binding band devices that combine a band member and a buckle member formed into a box shape as a whole are already known.

As shown in Japanese Utility Model Publication No. 54-40941, this binding band device combines a buckle member having two passages formed above and below and a band member to form a loop to bundle electric wires, etc. A locking piece having a locking protrusion that swingably projects inside the buckle member is extended, and the free end protruding outward from the buckle member is manipulated as necessary to bend the locking piece. The engagement between the locking protrusion of the locking piece and the locking protrusion provided on the band member can be released.

Certainly, this band device is advantageous in that it can be tied and untied freely, and that the band member can be formed continuously and then cut to a required length for use.

However, as a means for releasing the binding of this band device, a free end is formed continuously to the locking piece, and this free end is made to protrude outward from the buckle member to form a protrusion of the locking piece formed on the buckle member. Since the buckle member is configured to disengage from the recessed portion of the band member, there is a problem that the free end projecting outward from the buckle member may come into contact with something and come off.

In addition, the band member used in this band device has a concave portion formed on one side, and the locking protrusion of the locking piece provided inside the buckle member is engaged with the concave portion, so that the band member has no visible surface. There is a directionality on the back side, so when using this band device, it is necessary to check the direction of the band member.
The drawback was that the workability was poor. In particular, since the buckle member uses a fixed locking protrusion and a movable locking protrusion in combination, it is necessary to check the direction of the binding and the direction in which the band body is extended.

Furthermore, since the locking piece is extended outward from the buckle member to form a free end in order to release the engagement between the buckle member and the band member, the locking piece is molded quite hard. However, the operation of inserting the band member into the buckle member cannot be carried out smoothly, and the operability is quite poor especially in large band devices.In addition, in miniaturized devices, the free end of the locking protrusion is inserted into the band member. It is extremely difficult to release the mesh due to the heavy, tight fit.

[Purpose of the invention]

The present invention solves the disadvantages of the conventional band devices, such as easy disengagement, poor binding workability, and the need to confirm the directionality of the front and back sides of the band member and buckle member during binding work. In addition, it is an object of this invention to eliminate various drawbacks such as poor workability due to the free end of the locking projection being extended along the band member.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 to 3, the buckle member 1
is molded from synthetic resin such as nylon, and connects the center portions of the side walls 2 and 3 in an H shape with a partition wall 4, and further connects both sides with connecting walls 5 and 6. They are connected, and the whole is shaped like a box with bones.

Between the side walls 2 and 3 is a locking claw 7 whose one end (insertion side) is fixed by connecting walls 5 and 6.
8 is provided symmetrically with respect to the partition wall 4 connecting the center portions of the side walls 2 and 3. On the back of these locking claws 7, 8, operating parts 7a, 8a are connected to the connecting part 7.
It is provided so as to form a surface that is the same as the side wall portions 2 and 3 or a surface that is slightly lower than the side wall portion via the side walls 2 and 8e.

As shown in FIGS. 1 and 2, the locking claws 7, 8
The claw portions 7b and 8b at the tips of the holder are divided into two from the center by grooves 7c and 8c. This groove 7
C and 8c are portions that engage with guide walls of the band member, which will be described later, to reduce displacement of the band member in the longitudinal direction.

Guide passages 9, 1 for inserting the band member are provided between the locking claws 7, 8 provided on both sides of the partition wall 4.
0 is formed, and the band members are configured to be inserted in two stages, upper and lower, from the directions of arrows A and B.

As shown in FIGS. 4 and 5, the band member 15 has grooves 16 formed in two rows in the length direction on both sides, and force band parts 17 are formed on both sides of the grooves 16. It is configured to bear the tension of the band member. A guide wall 18 is formed between the concave grooves 16 arranged in two rows, and a groove 7 formed in the center of the locking claws 7 and 8 of the buckle member 1.
c, 8c (Fig. 1) are configured to engage with each other.

As shown in FIGS. 4 and 5, the band device according to the present invention has grooves 16 formed on both sides of the band member 15, so that it can be engaged with either side of the band member 15. It can engage with the stoppers 7 and 8.

Although the band member 15 has two rows of grooves 16 formed on both sides, the grooves 16 may be formed in one row.

Further, as shown in FIGS. 6 and 7, the band member 15A is inserted into the force band part 17, the horizontal band part 17b connecting the force band part 17, and the hole 16a formed by these parts. Therefore, a ladder-like structure can be used. Incidentally, the band member 15A in this embodiment can of course be used on both sides.

In the case of the band member 15A of the type shown in FIGS. 6 and 7, it is possible to manufacture one whose strength is increased by stretching.

That is, by narrowing the space between the horizontal band parts 17b to form the hole 16a to be horizontally long and narrow, and by extending the force band part 17 in the direction of arrow L to reduce its cross-sectional area, this can be achieved. It is possible to increase the strength of the force band portion 17 by three to four times that of the raw material (the original band member immediately after molding). Further, in this embodiment, by extending the horizontal band portion 17b also in the direction of arrow B, it is possible to improve the strength of the horizontal band portion 17b.

As shown in FIGS. 9 to 11, the guide passage 9

The band member 15 is pushed up by the protrusion 17a, and is inserted into the buckle member 1 while swinging in the direction of arrow H, and the claw 7b formed at the tip of the locking claw 7 is recessed. It is fitted into the groove 16 and locked. in this case,
The band member 15 is guided by both side walls of the guide groove 9, and is guided by the guide wall 18 and the claw portion 7b of the locking claw 7.
The grooves 7c provided between the two engage with each other to prevent the locking pawl 7 from moving laterally, and also to prevent it from coming off.

As shown in FIG. 8, the band member 15 inserted into the upper guide groove 9 of the buckle member 1 is wound around the object 20, and is inserted into the lower guide passage 10 as indicated by arrow M. The band member 1 is pulled while protruding from the guide passage 10, and a predetermined tension is applied to the band member 1.
5, the locking pawl 8 is inserted into the groove 16, engages with the protrusion 17a, and is fixed.

When removing the band member 15 from the buckle member 1, operate the operating part 7a or 8a in the direction of arrow J to bend the connecting part 7d or 8d and
By removing b or 8b from the groove 16, the engagement between the buckle member 1 and the locking claws 7 and 8 is released.

〔Effect of the invention〕

The binding band device according to the present invention is shown in FIGS. 1 to 3.
As shown in the figure (or Figures 9 to 11),
The locking claws 7 and 8 of the buckle member 1 are provided in a state where they are protected by the two side walls 2 and 3 constituting the buckle member 1, and the locking claws 7 and 8 of the buckle member 1 are provided in a state in which they are protected by the two side walls 2 and 3 constituting the buckle member 1. Operating portions 7a and 8a are provided on both sides, and the locking claws 7 and 8 are connected to the connecting walls 5 and 6, respectively.
It is supported between both side wall parts 2 and 3 by.

Then, as shown in FIGS. 4 and 5, the band body 1
5 is formed in the shape of a ladder, and is configured so that there is no distinction between the front and back sides.

Since both the buckle member 1 and the band body 15 have no vertical distinction, and the buckle member 1 is configured symmetrically with the partition wall 4 as the center, the band member 15 is different from the buckle member 1.
By simply inserting the end of the buckle member 1, it is possible to fix, insert and tighten the end of the buckle member 1 regardless of whether it is front or back or upper or lower, and also to release the end of the buckle member 1 regardless of whether it is the fixed end or the inserted part.

In particular, since both of the locking claws 7 and 8 can be operated using the operating portions 7a and 7b located apart from the band member 15, the engagement can be released extremely easily.

As shown in FIG.
e, 8e are planted, and operating portions 7a, 8a are provided at the ends of these connecting portions 7e, 8e.

The operation parts 7a and 8a are connected by the partition wall part 4 and are protected from protruding between the partition parts 2 and 3 which are arranged in parallel. Therefore, there is no possibility that the operation parts 7a, 8a will be operated inadvertently and the binding will be released.

Furthermore, even if something comes into contact with the operating parts 7a, 8a, the locking claws 7, 8 are supported in a cantilevered manner by the connecting walls 5, 6, so that the operating parts 7a, 8a
is simply pushed down in the direction of the arrow "b", and the locking claws 7, 8 hardly come off from the band member 15.

On the other hand, when releasing the locking claws 7 and 8, the operation parts 7a and 8a exposed on the surface of the buckle member 1 are
Since the release operation is performed by applying a mechanical force to the operating portion in the direction of arrow J, the release operation is extremely easy. This release operation can be performed from either end of the band member 15, and the release operation of binding and engagement can be performed without any hindrance, and can be used extremely effectively.
